What defines a cinder cone volcano?

A cinder cone volcano is characterized by its steep sides that are primarily formed from pyroclastic materials, such as volcanic ash, tephra, and cinders ejected during explosive eruptions. When these materials are expelled from a single vent, they fall back to the ground around the vent, accumulating and creating a cone-shaped hill or mountain. This unique structure contributes to the steep slopes that are a signature feature of cinder cone volcanoes.

While explosive eruptions and other volcanic features are relevant to the discussion of different types of volcanoes, the defining aspect of a cinder cone is the steep profile created specifically by the accumulation of pyroclastic debris. Other types of volcanoes, such as shield or stratovolcanoes, may have broader bases and different eruption styles.
